Hello, Short answer (mobile mail). On the whole a bug with a workaround is usually (understandably) less important to people than one without. I am slightly surprised that Canonical have not looked at this since I have provided a fix which may well be acceptable as is, but of course I do not presume to try to tell them what their priorities should be.
